Before Google bought it, companies knew there was no point in suing youtube as there was basically no money behind it. But since Google has acquired it they reall have to be more strict regarding copyrighted material to avoid all the lawsuits.

And Shepherds we shall be
For thee, my Lord, for thee.
Power hath descended forth from Thy hand
Our feet may swiftly carry out Thy commands.
So we shall flow a river forth to Thee
And teeming with souls shall it ever be.
In Nomeni Patri Et Fili Spiritus Sancti.
